Interpretation of Detrended Normal Q-Q Plot

[Jim Moffitt]

Sorry about the basic nature of the question, but can anyone tell me the
unit of measurement of the Y axis in a Detrended Normal Q-Q Plot?

It's the difference between an observation's expected z-score under
normality and its actual z-score.
